Chicken coop door has a sensor to open when it's light out. Problem is some mornings the battery is dying and door doesn't open. Controller has voltage from solar panels. So why do I need a battery. Can't Controller give power directly from solar panel?
Is there settings in Controller for this type of setup? Do I need a different controller? or should I switch panel wires on controller?
